Ok so... the mill (drill press?) is on the left and lathe on the right? Im still confused, if you clamp the alu down in a vice, what do you move across it to make the long cuts? Or do you clamp it to part of the mill that can slide, and use a special drill bit to slide the alu against to make the cut?

Sorry for the questions, Ive just always wondered about this.
